Answer 1

You can override AxisValueFormatter

i.e.:

xAxis.setValueFormatter(new AxisValueFormatter() {
            @Override
            public String getFormattedValue(float value, AxisBase axis) {
                return "YOUR_TEXT"; // here you can map your values or pass it as empty string
            }

            @Override
            public int getDecimalDigits() {
                return 0; //show only integer
            }
        });

You can pick center value of the group to map the group name, others are empty. that would be the easiest way.
